Also on the 9v battery clip, which wire is positive and which one is negative? And where do you solder it to?

Ground is "negative" part of the battery.

In DC (ie batteries) the - side is usually represented as ground ( for simple power/ motor circuits). and the + side is where the voltage is fed in from the + side of the battery

( Just to head off any rants. I know electrons technically flow from - )

On a battery each side is labeled + or -. On standard 9v US batteries the smaller terminal is +.
Its usually a good idea to get a connector that goes to the battery instead of soldering leads directly to the battery.

(I'm not promoting any particular site however it came up when I googled the connector, it has a picture, and the price looked good (cheaper than digikey))

Ground is normally -.  Electrons COME from - technically :P

Needless to say:

A long time ago, someone made a big oops. lol
